KMTA 28 Precision lock nuts with locking pin

Short Description:

KMTA precision lock nuts have a cylindrical outside surface and are intended for applications where high precision, simple assembly and reliable locking are required.

KMT and KMTA series precision lock nuts have three locking pins equally spaced around their circumference that can be tightened with set screws to lock the nut onto the shaft. The end face of each pin is machined to match the shaft thread. The locking screws, when tightened to the recommended torque, provide sufficient friction between the ends of the pins and the unloaded thread flanks to prevent the nut from loosening under normal operating conditions .

KMTA lock nuts are available for thread M 25×1.5 to M 200×3 (sizes 5 to 40)
